Static Friction
... object. The normal force is defined as the perpendicular component of the force exerted by the surface. In this case, the normal force is equal to the weight of the object. Once the box starts to slide, you must continue to exert a force to keep the object moving, or friction will slow it to a stop. ...

... In an oblique collision the velocity of one or both spheres is at an angle to the line of centres. It is often helpful to draw a diagram with the line of centres across the page. Example: A smooth sphere, A of mass m kg, is moving at a speed of 10 m s-1 when it strikes a stationary sphere, B of mass ...
